' To aZZ whom it mayconcem Be it known that I, ARcHin B. WALKER,

.acitizen of the United States, and a `resident Reproducing Instruments,

of the v'city of- Chicago, andState'of Illinois, .have invented certain new and useful Improvements in Sound-e of which the following is a specification.

My invention relates to improvements in sound reproducing instruments and more .especially to sound reproducinginstruments employed as 'a means forreproducing dictation by stenographers or typewriters, the object of the invention being to facilitate the reproduction of such dictation.V

The inventionconsists in the combinations and arrangements ofyparts lhereinafter described and claime The vinvention willbebest understood by .reference to the accompanying drawing forminga part of this specification, and in which v plan view ofa marking attachment attached to said instrument, and Fig. '3, a partial sec- Y I igure 1 is an end view of'a sound repro-^ ducmg .instrument with portions broken away andothers in section, Fig. 2, a top tion taken on line .fr-1m ofy Fig. 2.

The attachment'is shownasus'ed in con-4 junction with an ordinary sound reproduc` ing instrument. now on known-as the dictaphone This instru'- ment comprises asuitable ybase orbox l1 containing the operating mechanism of .the ina speaking tube 5,'

strument; a mandrel 2; a record cylinder 3 on said mandrel; a traveling carriage'4 and all arranged to operate inj "the usual manner, the carriage 4 being provided withthe usualm `sans for recording sound oncyl1nder-3'0r for audiblymeproducing said sound asfis usual in such ma- Asstated above the sound reproducing instrument is old andwell known, constit`utes`no part ofmy.presentfinventiom eX- `ceptfinso far as it tion and needs no .further description here.

enters intothe combina- The preferred fformof attaclimentiillus-l trated in the accompanying drawing constitutes a supporting. bracket or'arm secured kto the lower rear portion .of carriagec and county of Cook,

to permit the lower ends of the market vand the scale 19 being travelof plungers 12 and .13.

with the end of Iny use the instrument -isprepared for dicprojecting' forwardly under cylinder 3 to turned upwardly and 7 pivotally mounting va substantially U- .shaped plunger frame 8 thereon. The loweredges of frame 8 are provided with grooves 9 running on the upturned edges 10 of a channel member" 11 mounted atthe upper forward edge of.base 1. Two depressible spring held marking plungers 12 and 13 are mounted to slide vertically in frame 8 so as said plungers to contact with the bottom ofchannel member '11. Each of the pl-un'ger's 12 and'13 is provided'at its lower end with a ma-rking head 14, said marking heads being provided with distinctive marking means, in the present instance, plunger 12 being provided with means for printing an arrow and plunger 13 for printing a pointing finger.- .An inking roller 15 is mounted in angular swinging arms 16 pivoted to lframe 8 and is normally held in operative relation with the marking heads 14 by-means of a spring 17, the ,arrangement being'suchthat when either of the `plungers 12 or 13 is depressedthe corresponding marking head with ink and at the same time roller 1 5lwill be automatically swung out ofV the path of said plunger to permit of free depression thereof as indicated by` dotted linesin Fig. 3. A removable-strip of paper 18 is placed in the bottom of channel member-'11 and vis provided with a centrally arranged scale 19 arranged to represent the length of travel .of carriage 4 and conse- 14 vwill be suppliedv quently corresponding with the usual 'indic ator scale 19 and being positioned between the paths of A stop flange 20 is arrangdat one end of channel member 11 and serves as a'fmeans for accurately positioning scale 19 with its zero in registration with the starting point of carriage V`4 and its highest said trave tation in the'usual manner and a paper'strip 18 bearing the scale 19 is positioned in chan- Anel 11.. The dictation is then commenced and continued in the usual manner. When `graduation in registration provided on the instrument,

an error is made in the dictation or other occasion arises for caution to the typist who is to reproduce the same, the travel of carriage 4 is momentarily stopped and plunger 13 depressed to print a pointing finger 21 on strip 18 adjacent scale 19. At the termina tion of the dictation the carriage is again stopped and plunger 12 is depressed to print an arrow 22 on the other side of scale 19 to'indicate the termination of the dictation. Thus the scale marked as shown in Fig. .2 would indicate that an erior had been madeat point 20 and that the dictation had ended at point 25 of scale 19. Further dictation may be continued until the corresponding record cylinder is entirely used up' and similar indicating marks made on stripv 18. If the same instrument is used in reproducing the dictation a visual record is strip 18 is removed with the cylinder 3 andA serves to notify the operator as to the places in the dictation where caution must be exercised. n

. While I have illustrated and:y described the ypreferred form of vconstruction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention.

I, therefore, do. not wish to be'limited to the precise details of construction set forth, but desire to-avail myself of jsu'ch variations land modifications as come within thelscope -of the appended claims.V

I Having described my invention what I the lines bf travel of said plungers, substantiallyI as described.v V

3. In combination a Asound reproducing instrument traveling carriage; a support- -lng bracket secured toV said carnage; a,

plunger frame pivotally 'connected with said bracket; afchannel'support for said plunger frame, there being notches in the lower portion of. said frame'riding on the edges of said channel; two depressiblespring held marking plungers mounted in said frame and adapted to contact with the bottom of said channel; distinctive marking elements on the bottoms of said-plungers; a spring held inking roller normally contacting with said marking elements but arranged to be automatically swung from the path of said plungers upon depression thereof; and a strip of paper arranged in said supporting channel' and provided with a centrally positioned scale arranged between the paths of tra-vel of said 'p'lungers, substantially as described.,

4. In combination a sound reproducing traveling carriage; a supporting bracket secured to said carriage; a marking frame pivotally -connected with said'b-racket; a support upon which said frame rides; a marking element on said frame; and a niark receiving element on said support in operative relation with said marking element, substantially as described.

5. In combination a sound reproducing traveling carriage; a supporting bracket secured to said carriage; a marking frame pivotally connected with said bracket; a spring held depressible plunger on said frame; a marking element on the bottom of said plunger; a springheld inking roller normally contacting withsaid marking element but arranged to be automatically swung from the path of said plunger upon depression thereof; and a mark receiving element 1n operative relatlon w1th 4said marking element, substantially as described.

6. In combination a sound reproducing traveling carriage; a supporting bracket secured to said carriage; a marking frame pivotally connected with said bracket; a support upon which said frame rides; a spring held depressible plunger on said fra-me; a marking element on the bottom of said plunger; a spring held inking roller normally contacting with said marking element but arranged to be automatically swung from the path of said'plunger upondepression thereof; and a mark receiving element in' operative relation with said marking element, substantially as described.

7. In combination a sound reproducing traveling carriage; a supporting bracket secured to said carriage; a spring held depressible plunger on said. bracket; a marking element on the bottom of said plunger; a spring held inking roller normally con- 'tacting with said marking element but arranged to be automavically swung from the path of said plunger upon depression thereof; and a mark receiving element in operative relation with said' marking element,

substantially as described.
